i want to know about algebra?

Answer 1

Algebra is a branch of mathematics concerning the study of structure, relation and quantity. The name is derived from the treatise written by the Persian mathematician Muḥammad ibn Mūsā al-Ḵwārizmī titled Al-Kitab al-Jabr wa-l-Muqabala (meaning "The Compendious Book on Calculation by Completion and Balancing"), which provided symbolic operations for the systematic solution of linear and quadratic equations.

Together with geometry, analysis, and number theory, algebra is one of the several main branches of mathematics. Elementary algebra is often part of the curriculum in secondary education and provides an introduction to the basic ideas of algebra, including effects of adding and multiplying numbers, the concept of variable, definition of polynomials, along with factorization and determining their roots.

Algebra is much broader than elementary algebra and can be generalized. In addition to working directly with numbers, algebra covers working with symbols, variables, and set elements. Addition and multiplication are viewed as general operations, and their precise definitions lead to structures such as groups, rings and fields.

Answer 2

Some people say algebra is math with letters rather than numbers. This isn't totally true. Letters are used, but they stand for numbers. The problem is knowing what number they stand for.

In algebra, there's an idea called "variables". Basically, this is some number that you don't know, and therefore you have to find. Here's a really simple algebra problem.

5 + 5 = x

In here, x is the variable. We "solve" for the variable by putting x on one side of the equal sign and a number on the other. Here, we know that 5 + 5 = 10, so we know x = 10.

Equations can sometimes be scrambled around too... You can manipulate equations to get only the variable on one side. Basically, you can do almost anything, as long as you can do it to both sides. For example, you can add or subtract a certain quantity from both sides, or multiply or divide by the same number, or raise both sides to the same power. Here's another way to write that same equation from before:

x - 5 = 5
Add 5 to both sides...
x - 5 + 5 = 5 + 5
x = 10.

Later on, you can get equations with more than one variable, or a set of two or more equations called a "system of equations". You can also graph equations. It sounds really complicated, but if you're taught it well, it's actually not too bad.

Answer 3

What about it?
Algebra shows you a systematic way of solving problems. What you do to one side of the equation you must also do to the other side.
There are only 4 things you can do in any math problem. Add, subtract, multiply, and/or divide.
It's pretty easy once you get the hang of it. Having a good teacher makes all the difference in the world.

Answer 4

Algebra is another form of Arithmetics where letters are used for numbers.
